Blowout at Cape Station: Fervo Energy’s First Major Crisis After Blockbuster IPO

Just weeks after a record-breaking IPO, the flagship project of the "geothermal unicorn" faces its first major operational crisis. By : Robert Buluma   Beaver County, Utah – The morning of May 27, 2026, began like any other at the Cape Station construction site in rural Utah. Workers for Fervo Energy, the newly public darling of the renewable energy world, were engaged in the complex task of drilling deep into the Earth’s crust to unlock what the company promised would be the future of 24/7 clean power. But by the afternoon, the routine had turned into a crisis. The site had experienced a blowout—an uncontrolled release of fluid or pressure from a well. For any energy company, a blowout is a serious matter. For Fervo Energy, which had just raised $1.89 billion in a blockbuster Nasdaq debut two weeks prior, it represents an immediate stress test of its technology, its safety protocols, and its $7.7 billion market valuation. While the well has since been contained and no injur...

Eavor Geretsried Geothermal Breakthrough: Inside the Closed-Loop Energy Revolution, Drilling Challenges, and Path to Scalable Clean Power

The Geothermal “Holy Grail” Just Got a Reality Check: Inside Eavor’s Geretsried Breakthrough By: Robert Buluma   May 22, 2026 It’s not every day a deep-tech energy company publishes a detailed technical report that openly documents what went wrong on its flagship project—and still comes out looking stronger. That’s exactly what Eavor Technologies did with its Geretsried geothermal project in Bavaria, Germany. The result is unusually transparent: part technical post-mortem, part validation of a technology many have doubted for years. And the core message is simple. They built it. It works. But it wasn’t smooth. The short version Eavor is trying to solve one of geothermal energy’s hardest problems: how to produce reliable heat and power anywhere, not just in rare volcanic hotspots. Their claim has always been bold: a closed-loop geothermal system that is scalable, dispatchable, low-carbon, and independent of natural reservoirs. Critics have long argued it wouldn’t survive...

Eavor steps back from operator role in the Geretsried geothermal project

Eavor at the Crossroads: What Geretsried Really Tells Us About the Future of Closed-Loop Geothermal By Alphaxioms Geothermal Insights | May 13, 2026 For years, Eavor Technologies was the geothermal sector's most talked-about enigma. The company raised hundreds of millions of dollars, attracted backing from heavyweights including BP , Chevron , Helmerich & Payne , and Temasek , and made bold promises about a proprietary closed-loop technology that would quietly revolutionise how humanity extracts heat from the earth. But it rarely said much in public. The secrecy was, to many observers in the geothermal community, a feature rather than a bug — protecting intellectual property, managing competitive intelligence, buying time. Now, Eavor is talking. And what it is saying is worth listening to very carefully. In an exclusive interview published on May 13, 2026, by GeoExpro editor Henk Kombrink, Eavor's new president and CEO Mark Fitzgerald — who took the role in October 2025 ...

Rodatherm Energy: The Refrigerant Gambit

By: Robert Buluma   Rodatherm Energy has done something no other geothermal startup has attempted at commercial scale: swapped water for refrigerant in a closed-loop system. The claim is 50% higher thermal efficiency than water-based binary cycles, achieved by circulating a proprietary phase-change fluid through a fully cased, pressurized wellbore. The company emerged from stealth in September 2025 with a $38 million Series A—the largest first venture raise in geothermal history. Lead investor Evok Innovations was joined by Toyota Ventures, TDK Ventures, and the Grantham Foundation. The engineering thesis is elegant. The execution risks are significant. This is an Alphaxioms examination of both. II. The Thermodynamic Distinction Every geothermal company you've covered moves heat using water or steam. Rodatherm moves heat using a fluid that boils and condenses inside the wellbore. In a conventional closed-loop water system (Eavor's model), water circulates as a single-phase liq...

Globeleq’s 35MW Delay Deepens Kenya Power Rationing Crisis

Globeleq Delays Power Supply: Kenya's Energy Crunch Worsens By Robert Buluma   Published: May 29, 2026 There is an uncomfortable truth settling over Kenya’s electricity sector this week. Just as the country’s industrialists were beginning to breathe a sigh of relief that the worst of the power rationing might be over, a new storm has appeared on the horizon. The British independent power producer, Globeleq, has officially delayed the connection of its 35-megawatt geothermal plant to the national grid. For the average Kenyan who has grown accustomed to the lights flickering off precisely at 6:30 PM, this might sound like just another technical footnote in a long list of energy sector woes. But for those who watch the numbers closely, this is a significant blow. It is a delay that threatens to prolong the agony of scheduled blackouts, pressure Kenya Power’s already strained finances, and expose the fragility of a national grid that is struggling to keep pace with a growing economy....
